A COMPARISON OF RAIN GAGE AND DUALFREQUENCY RADAR DATA OF PRECIPITATION.

Abstract

A dual-frequency radar system of 3.2-cm and 10.3-cm wave lengths was used to measure the reflectivity of a storm cell. The relationship between radar reflectivity, Z, and rainfall rate, R, permits computation of R when Z is measured. In this study, correlation coefficients were computed between measured R and observed Z. The radar pattern is fitted to the actual rainfall intensity pattern. This method, at present, does not lend itself to quantitative measurement of rainfall intensity; however, reliable estimates of the rainfall distribution are possible.
